Sugar Free Butter Cream Icing

Detailed Directions (with Pictures)

*Please note there is a printable recipe card at the end*

A great habit is to set everything out we am going to need for the recipe beforehand. Here we have our pre-cut room temperature butter, six medium-sized eggs, erythritol, and vanilla.

Good to go!

Sugar Free Butter Cream Icing Ingredients

This recipe calls for 6 egg whites, so we need to separate those from the yolk, you do that by gently tossing the yolk back and forth between the two half’s of the cracked egg, letting the white fall down into the bowl.

Egg Whites,

Do your best not to let any of the yolk get into the whites, don’t panic if you do but it helps to keep it out.

You can also try lighly cracking the egg enough to let the yolk run out on its own, if the tossing back and forth is not working for you.

Separate Egg Yolk From Whites

Next we will want to set a small pot of water on the stove to start simmering, this is to be used as a double boiler, so if you have one, please use it.

If not, no worries. A small pot and bowl that fits snugly over the top works just fine.

Simmering Water

Just make sure the level of the water and the bottom of the bowl are at a good level and do not touch each other, we want the seam to help melt the erythritol if the water starts to boil it will cook our eggs, which we do not want!

Leveled Bowls

Now that we have that all squared away, we can now add in our egg whites and erythritol.

Egg Whites And Erythritol
Add Erythritol

Whisk that together while the erythritol melts into the egg whites.

Mix While Erythritol Melts Into Egg Whites

It will start to foam a little from all the mixing, that’s fine.


To test if it is ready, rub the mixture between your fingures to test for grittiness. If you can still feel the erythritol, keep cooking! If it’s as smooth as a baby’s bottom, we can move to the next step.

Don’t worry about burning your fingers, it shouldn’t be more then warm as we are not applying the direct heat.

Test If It Is Ready

Pour the mixture into a large mixing bowl that is room temperature.

Mixture In The Bowl

Whip the egg white mixture on high for approximately 15 minutes

Whip The Eggs Mixture

We want to have a nice fluffy meringue that is firm in its form.

Fluffy Mixture

At which point we can slowly add in our cubes of butter, one at a time. Waiting until each cube is fully combined before adding in the next.

Add Cubes Of Butter

The beautiful fluffy meringue will flatten out into more of a creamed icing once adding in the butter, no need to fret, that’s what we want.

Creamed Acing

If for some reason you’re butter icing cream doesn’t look like this and is a but more soupy, just place it in the fridge for 5 to 15 minutes and then whip up again. Sometimes if the butter is added to quickly or is too soft that can happen.

After we have a nice whiped cream icing we can add in our vanilla for flavoring.

Scoop Of Vanilla Flavour

You can add in any flavoring of your liking, this butter cream is a wonderful base for almost anything! We would recommend staying away from oil based flavorings as they do something a little funky to the consistency.

Voila here we have beautiful light vanilla ‘Swiss Maringue Butter Cream Frosting’. Perfect for so many deserts, enjoy.

Sugar Free Butter Cream Icing

Easy to make sugar free butter cream icing.


  • 6 medium-sized egg whites
  • 1 cup of erythritol
  • 1 cup of butter
  • 2 tsp. of vanilla


  1. Combine egg whites and sugar whisk together
  2. In a double boiler, once the water is simmering lightly add mixture into the top bowl or top boiler pot.
  3. Stir until the erythritol is fully melted, takes approx 5 minutes. Test yolk mixture with fingers to make sure there is no grittiness. Keep stirring until smooth. Do not boil until the eggs will begin to cook.
  4. Once smooth from the double boiler, transfer it into a large mixing bowl that is room temperature.
  5. Whip on high approximately 15 minutes. Until high foam thickness in a meringue form.
  6. Slowly add in one cube of room temperature butter waiting until it is completely mixed, the meringue will flatten and turn into more a cream base now. Keep adding in the butter until it’s all incorporated.
  7. Whip on high for 2-3 minutes to fluffen up the icing. While mixing add in vanilla, you may also add in other desired flavoring. I recommend staying away from oil-based flavors. You can even add in a little bit of melted chocolate if you want a richer flavor.
  8. If while mixing in the butter your icing went a tad soupy, set in the fridge for 5-15 minutes and whip again. All is not lost.


Mix all the ingredients, even you can add melted chocolate for more amazing flavor, whip it and use this sugar-free buttercream icing for your deserts.
